Influence of Cold on Radiostrontium Excretion

IN most work on the problems of releasing radiostrontium which has been incorporated into the vertebrate skeleton the effects of various parenterally administered chemical agents on the excretion rate of radiostrontium have been studied. Someriecrease in skeletal retention was obtained when inactive salts of strontium^1–4 or zirconium⁵ were given almost simultaneously with radiostrontium; so far all other efforts have been practically useless.
